Discipline is the eighth studio album by English progressive rock band King Crimson, released on 22 September 1981 by E.G. Records in the United Kingdom and by Warner Bros. Records in the United States. This album was King Crimson's first album following a seven-year hiatus. Only band co-founder and guitarist Robert Fripp and drummer Bill Bruford remained from the previous incarnation. They were joined by two American musicians: guitarist, vocalist and lyricist Adrian Belew and bassist and backing vocalist Tony Levin. The album featured a more streamlined, new wave influenced sound. Discipline has been described as art rock, progressive rock, new wave, post-progressive, and dance-rock. The title of the ballad "Matte Kudasai" means “please wait” in Japanese (待って下さい). The original release of Discipline featured a guitar part on this track by Robert Fripp that was removed from subsequent releases of the album starting with the 1989 Definitive Edition remaster. The 30th and 35th anniversary editions, meanwhile, include both versions of the song. The lyrics of "Indiscipline" were based on a letter written to Adrian Belew by his then-wife Margaret, concerning a painting that she had made. "Thela Hun Ginjeet" is an anagram of "heat in the jungle". When it was first performed live, some of its lyrics were improvised around an illicit recording made by Robert Fripp of his neighbours having a vicious argument when he was living in New York; this recording is featured on the track "
